Sahlgrenska University Hospital (SU) is one of the major hospitals in Europe
and was founded in 1997 when three hospitals in Sweden merged; Mölndal
Hospital, Sahlgrenska Hospital and Östra Hospital. Sahlgrenska provides emergency
and basic care within the city of Göteborg with 700,000 inhabitants, as
well as highly specialized care for the Västra Götaland county with 1.7 million
inhabitants.

Every year, Sahlgrenska University Hospital records two million referrals and
comments through the Central Registry system which is powered by MySQL.
All in all, the Central Registry manages about 100 gigabytes of data with up
to 2,000 concurrent users on a yearly basis. Moreover, Sahlgrenska's various
care units have different requirements regarding the set up of the patient's
medical profile within the Central Registry, which calls for a flexible and
adjustable database solution.
